Will the 622 work with a legacy quad LNB?

[ken]

I'm not sure why the 622 is not part of the Tivo lawsuit but in the event my 721 is shut down I will be ordering a 622. Will be needing one soon anyway even without the Tivo crap so I was wondering if it will work with my DISH 500 that has an old legacy quad that is feeding my721 and 5000.

Yes it will work, you'll need two feeds to the receiver and when a check switch is run, it will go through 38 tests instead of the normal 2 or 3 with dish pro.
